That seems like a great plan to me.
I also use the Polemaster most consistently. I also have used the NINA 3-point PA (TPA) and the PHD2 Drift Align. To me the Polemaster is the most consistent and the fastest. I have found that If I use any of those methods and I require a large initial adjustment to dial in the alignment, I will use the first iteration of the alignment to get it pretty close and then restart the alignment again from scratch. This tends to give me more accurate and more repeatable results. If you use the NINA TPA I would read through the documentation for recommendations. Personally I find the pointing declination about 35-50 degrees from Polaris works most consistently for me but your mileage may vary.

If I leave my mount set up on the back porch, I find I generally do not have to re-align each night, but rather, I will cold start the mount at CWD, open PHD2 through NINA, use calibration assistant (Tools > Calibration Assistant) to slew to the meridian at 0 declination, and then I cancel the calibration (I reuse mine) and run guiding assistant instead (Tools > Guiding Assistant) for 2-5 minutes.
I find this functions as a "check" of my unguided performance for the night, it gives me a easily understandable reading of my polar alignment error, and gives recommendations for my PHD2 sensitivity based on the seeing. I like to see "less than an arc second" but I accept anything up to about 6 arc seconds with my 1300mm focal length. If it is more than that I reattempt polar alignment.
